Versuchsvorschrift
5-(2-Chloro-5-nitro-benzoyl)-1H-pyrrole-2-carboxylic acid (200 mg) (Example 63) was converted to 5-(2-chloro-5-nitro-benzoyl)-1H-pyrrole-2-carbonyl chloride using oxalyl chloride at room temperature for one hour. It was then condensed with 3-amino-phenol (170 mg, 1.7 eq.) and TEA at room temperature for 1.5 hrs to give 135 mg of 5-(2-chloro-5-nitro-benzoyl)-1H-pyrrole-2-carboxylic acid (3-hydroxy-phenyl)-amide.
